Bulk Erase
Part 1 – record audio out and verify 400 Hz bulk erase tone.
Part 2 – record audio out and verify absence of bulk erase tone during rotor data
output.
Part 3 – record audio out and verify absence of bulk erase with recording disabled.
Example report message(s):
08:02:42 PASSED Bulk Erase #1 (Expected 400 Hz) Results = 400.0 Hz
08:02:50 PASSED Bulk Erase #2 with active Rotor Speed (Expected <> 400
Hz) Results = 123.0 Hz
